WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 405,062, dated June 11, 1889.

Application filed January 26, 1889. Serial No. 297,698. (No model.)

To all whom t may Concern.;

Be it known that I, LESLIE VETHERBEE, of Clayton, in the county of Lenawee and State of Michigan, have invented a new and Improved VVagon-Brake, of which the following is a full, clear, and exact description. Y

The object of the invention is to provide a new and improved brake specially intended for front wheels of wagons and automatically operated from the neck-yoke.

The invention consists in certain parts and details and combinations of the same, as will be described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a partof this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a plan view of the improvement with parts in section. Fig. 2 is a side elevation of the same with parts broken outand parts in section, and Fig. 3 is a sectional side elevation of part of the improvement on the line :l: x of Fig. l. Fig. 4 is an enlarged sectional end elevation 0f the brake-block.

The wagon A is provided with the front wheels B, mounted to rotate' on the axle C, supporting the hounds D, of any approved construction. To the rear end of the hounds are secured rearwardly-extending brackets E, to the under side of which are pivoted links F F, also pivotally connected at their lower ends with longitudinally-extending plates F', fastened by means of clips F2 to the brakebeam G, extending transversely in the rear of the front wheels B B. The links F permit a forward and backward swinging of the brake-beam G.

The brackets E are preferably bolted to the hounds D, and are provided with additional boltfapertures E', to shift the brackets forward or backward To bring the brake-blocks in proper position in regard to the wheels.

Near each outer end of the brake-beam G are secured by clips or other means the vbearings H, in which are mounted to turn shafts H and H2, located one above the other, and carrying at their outer ends arms HS and H4, extending toward the front wheels B, and carrying a brake-block I for each wheel B. The lower shafts H2 are somewhat longer than the upper shafts H, and on each is coiled a spring H5, fastened by one end to the shaft and by its other end to one of the bearings H. The

springs H5 serve to hold the brake-blocks I 55 out of contact with the front wheels B when the wagon is backed up and it is not desired to apply the brakes.

Each of the brake-blocks I is provided with two side plates I and I2, of which the latter is provided with a block l2, extending to the inside of the other plate I. A brake-shoe I4 is held in place between the two plates I and I2 by a bolt l5, held on the plate I and passing through the' block l2 and side plate I2. A nut I6 screws on the outer end of the bolt I5 against the plate I2, and serves to clamp the side plates I and I2 tightly ontothe brake-shoe I4, so as to hold the latter in place. The brakeshoe I4 abuts at its inner end against the front end of the block I2, and can be easily removed and replaced by loosening the nut l( of the bolt I5.

On each outer bearing I-I is secured an arm H, having an outwardly-extending lug H7, passing over the uppermost arm H3 of the shaft H. The lug H7 serves to prevent the arm H3 from swinging too far upward.

To the brake-beam G are pivotally secured the branch arms J of the rod J, extending forward under the hounds D and provided near its front end with a hook J2, into which hooks a chain J 2, passing over a pulley J 4, secured on ashaft J 5, mounted to rotate in suitable bearings J G, secured to the pole K of the usual length and mounted to slide in suitable bearings on the hounds D. .The bearings J6 project downward, so that the shaft J 5f is below the pole K. On the shaft J5 is also secured a larger pulley J 7, over which passes a chain J 2, secured by one end to the periphery of the said pulley, and then extending forward onto the pole K, to passv over a pulley J 9, mounted to rotate in suitable bearings in the front end of the pole K. The outer end of the chain J s is passed rearward and upward and connected with the neck-yoke Luheld in any suitable manner on the front end of the pole K.

The rod J, before mentioned, is pivotally connected near its front end with' a lever N,

fulcrumed at N on a rear bearing N2 of the pole K, said bearing N2 being secured to the hounds and the fth-wheel, as is plainly shown in Figs. 1 and 2.

The upper end of the lever N is pivotally ICO connected by a link O with a bar P, mounted to slide in suitable bearings K on the top of the pole K. On thebarP is formed a U -shaped keeper P through which passes the doubletree Q, to which the horses are hitched, said doubletree Q being pivoted on the bolt PL passing through the keeper P and through a slot K2 extending longitudinally in the pole K. The bolt P2 slides forward and backward with the keeper P 5 but this fmovement is limited by the length of the slot K2, through which the said bolt passes.

The operation is as follows: As illustrated in Figs. l and 2, the brake is off, and is held in this position by the action of the springs H5. The horses pulling the wagon A are hitched tothe doubletree Q and the neck-yoke L in the usual manner, and when the wagon passes down an incline the horses pull the neck-yoke rearward, so that the chain J s rotates the pulley J 7 in the direction of the arrow a', whereby the chain J 3 is wound upon the pulley J 4 on the same shaft J as the pulley J 7. The winding up of the chain J 3 causes a forward motion of the rod J, so that the brake-beam G is moved in the same direction, swinging on the links F, supported from the hounds. The swinging motion of the brake beam G throws the brake-blocks I, with the brake-shoes Il, in contact with the front wheels B, whereby the wheels are braked. The forward motion of the rod J causes a swinging of the lever N, so that the link O is pulled rearward, and thereby moves the rod P and the doubletree Q in the same direction until the bolt P2 rests against the rear end of the slot K2 in the pole K. lVhen the wagon has passed onto level ground,the horses commence to pull on the doubletree Q, so that thekeeper P with the rod P, is moved forward, thereby exerting a forward pull on the link O, which causes the lever N to swing, whereby the rod J is moved rearward. This motion causes a rearward swinging motion of the brakebeam G, so that the brake-blocks I are thrown out of contact with the front wheels B. When the wagon is backed up, the horses exert a pull against the neck-yoke L in the same manner as above' described, so that the brakeblocks l are thrown toward the front wheels B; but as the latter turn in the opposite direction the brake-blocks are held out of contact by the action of the springs ll5. Thus it will be seen that the wagon is automatically braked from the neck-yoke when it passes down an incline, and the brake is thrown ofi' automatically the moment the horses begin to pull on the doubletree.

The `brake, as shown, is attached to platform-wagons, but may equally well be adapted for other styles of wagons, such as lumberwagons, &c.

l-laving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a wagon-brake, the combination, with the pole and the neck-yoke held thereon, of a brake-beam connected with the said neckyoke and mounted to swing, arms held to turn on the said brake-beam, and brake-blocks pivotally connected with the said arms, substantially as shown and described.

2. In a wagon-brake, the combination of a brake-beam suspended from the rear ends of the hounds by means of apivotal connection, and brake-blocks pivotally connected to the beam, substantially as described.

3. ln a wagon-brake,the combination, with a brake-beam mounted to swing, of a set of parallel arms mounted to turn on each end of the said brake-beam, and a brake-block pivotally connected with the outer ends of each set of the said parallel arms, substantially as shown and described.

4. In a wagon-brake, the combination, with a brake-beam mounted to swing, of a set of parallel arms mounted to turn on each end of the said brake-beam, a brake-block pivotally connected with the outer ends of each set of the said parallel arms, and a spring held on eachv set of parallel arms to hold the said brake-blocks out of contact with the wheels when backing up the wagon, substantially as shown and described.
